Unresolved inclusion in OpenCV+Android tutorial

Hi,

I have followed the tutorial to run the mixed native code and java, installed the ndk stuff, and it works nicely. But in the files at jni directory the Eclipse always show a "Unresolved inclusion: <jni.h>" and other unresolved messages like as "Unresolved inclusion: <opencv2 core="" core.hpp="">".

I have searched on the net, and says that I should include, in c/c++ properties. But the tutorial examples of OpenCV+Android are not c++ projects. C/C++ perspective does not apply to these projects and I don't find in any place of Eclipse how to include, even switching to c/c++ perspective. I have the plugin cdt installed.

How I could handle it? Thanks!

If you open Proj Prop-s -> C/C++ General -> Paths and Sympols -> Include tab, you'll find that the project has already some include dir-s set up, but that's not enough...

I managed to fix the code indexer errors by adding one more include dir there: press Add... -> paste the following path ${NDKROOT}/sources/cxx-stl/gnu-libstdc++/libs/armeabi-v7a/include, check Add to all cfg and press OK, agree to re-indexig.

The following link at stackoverflow solves the problem. I get rid of the unresolved stuff, but a bunch of gcc errors appears. Anyway, for this specific question, is solved.
